Embodiment 1 FIG.
FIG. 1A shows a perspective view of a wire rod winding device (communication cable winding device) according to Embodiment 1 of the present invention when a wire rod 100 such as a communication cable is wound up. FIG. 1B shows a plan view corresponding to FIG. In addition, in FIG. 1, only the periphery of the base 1 is extracted and shown among each structure of a wire winding apparatus.
The wire winding device includes a pedestal 1, a column 2 with one end fixed to the pedestal 1, a support plate 3 with the other end fixed to the column 2, and a plurality of shafts 4 a to 4 d with one end fixed to the support plate 3. And the one part is comprised by the wire rod clamping part 5 which clamps the end of the wire 100 wound with a wire rod winding apparatus. The pedestal 1, the pillar 2 and the support plate 3 constitute a support member.

The pedestal 1 is provided with a shaft hole 1a, and a rotation shaft (not shown) of a motor (drive unit) having an axis parallel to the shafts of the plurality of shafts 4a to 4d is fitted into the shaft hole 1a. Thus, the base 1 is configured to rotate integrally with the rotation shaft of the motor. Further, since one end of the column 2 is fixed to the pedestal 1 and the other end is fixed to the support plate 3, and one end of the plurality of shafts 4 a to 4 d is fixed to the support plate 3. In addition, the pillar 2, the support plate 3, and the plurality of shafts 4a to 4d also rotate integrally with the rotation shaft of the motor. Of course, the wire pinching portion 5 fixed to the base 1 also rotates integrally with the rotating shaft of the motor. A winding part is comprised from a drive part and the said support member.
In addition, if the operation | movement which winds the wire rod 100 to the some shaft 4a-4d which is mentioned later is possible, the axis | shaft of the some shaft 4a-4d may be substantially parallel or inclined with respect to the rotating shaft of a motor. Good.

  The wire rod 100 is wound around the plurality of shafts 4a to 4d of the wire rod winding device, and a certain amount of tension is applied by the wire rod feeding portion 6 on the way to the end portion that is not clamped by the wire rod clamping portion 5. It is held with it. The end of the wire 100 that is not sandwiched by the wire sandwiching portion 5 is wound around a free end or a reel drum.

The operation of winding the wire 100 by the wire winding device having the above configuration will be described.
First, one end of the wire rod 100 held by the wire rod feeding portion 6 is held by the wire rod holding portion 5. For example, this is achieved by providing the wire winding device with an arm portion (not shown) composed of a mechanical element such as a motor that can be gripped near one end of the wire 100 and moved to a predetermined position. .
Subsequently, by operating a motor whose rotating shaft is fitted in the shaft hole 1a of the pedestal 1, the plurality of shafts 4a to 4d are integrally rotated, and the wire 100 is wound around the plurality of shafts 4a to 4d. . The number of rotations of the motor is appropriately set in consideration of the length of the wire 100 to be collected as a bundle, the interval at which the shafts 4a to 4d are installed, and the like.

When the motor rotates a predetermined number of times, the wire rod 100 wound around the plurality of shafts 4 a to 4 d is subsequently bundled using the bundle band 71. For example, as shown in FIG. 2, the bundled part 7 is moved to the vicinity of the wire 100 wound around the plurality of shafts 4 a to 4 d by a cylinder (not shown) or the like and bundled by a bundled band 71. Do. The bundling unit 7 may be configured using a known bundling machine or the like, and detailed description thereof is omitted.
After bundling, the wire 100 is cut at a position in the vicinity of the wire feeding section 6 and then removed from the plurality of shafts 4a to 4d and is bundled by the bundle wire band 71. This is performed by, for example, a cutter (not shown) included in the wire winding device, and an arm portion (not shown) made of mechanical elements such as a motor that can grip and move the bundled wire 100. Is called.

Here, the details of the shafts 4a to 4d will be described.
As shown in FIG. 1 (a), the shafts 4a to 4d have a cylindrical shape, but a curved portion, which will be described later, whose diameter is gradually reduced once in the axial direction and gradually returns to the original diameter. 41a-41d are formed. The wire 100 is wound around the curved portions 41a to 41d of the shafts 4a to 4d by adjusting the relative positional relationship between the wire feeding portion 6 and the plurality of shafts 4a to 4d.
FIG. 3 is a cross-sectional view showing a state where the wire 100 is wound up by the wire winding device according to the first embodiment and bundled with the bundle band 71. In the shafts 4a to 4d, the cross sections when cut along a plane including the axis are recessed in an arc shape by the curved portions 41a to 41d (FIG. 3A).

FIG.3 (b) has shown the state at the time of winding up the wire 100 with the shafts 4a-4d, and is wound by winding the wire 100 along the curved parts 41a-41d of the shafts 4a-4d. envelope S ₁ of the entire cross section of the wire 100 is substantially circular.
In addition, the magnitude | sizes of the curved parts 41a-41d are designed so that the wire 100 may be accommodated in the curved parts 41a-41d of the shafts 4a-4d and wound up. This is based on the distance between the shafts 4a to 4d and the length of the wire 100 that is to be bundled together by the bundle band 71 and integrated into one shaft. What is necessary is just to design the magnitude | size of the curved parts 41a-41d according to this assumption supposing whether it will wind (in the example of FIG.3 (b), the cross section for eight is wound). Naturally, as the number of the wires 100 wound around the shafts 4a to 4d increases, the curved portions 41a to 41d are formed larger.

FIG. 3C shows a state in which the wound wire rod 100 is bundled by the bundle wire portion 7, and is bundled along the outline S _{1 of the} entire cross section of the wire rod 100 that is substantially circular. A band 71 is wound.
FIG. 3D shows a state when the wire rod 100 bundled with the bundle wire band 71 is removed from the shafts 4 a to 4 d, and thereafter, the wire rod 100 is bundled by the bundle wire band 71 as a bundle. Will be handled in the specified state.

Conventionally, as shown in FIG. 6, the shaft 11 around which the wire 100 is wound has a linear shape. Therefore, the outline S < _b > _{2 of the} entire cross section of the wire 100 is bundled in a substantially trapezoidal state. Therefore, the wire 100 which are combined as a bundle by wire bundle band 71 is handled as, collapse the entire cross-section of the envelope S ₂ which has been organized into a substantially trapezoidal, sufficient flux line state bundled band 71 eventually Couldn't keep up.

On the other hand, in the wire winding device according to the first embodiment, the shafts 4a to 4d have the curved portions 41a to 41d, and the wire 100 is wound around the curved portions 41a to 41d. envelope S ₁ of the entire cross section of the wound wire rod 100 is substantially circular. That is, the wire rods 100 are aligned in a shape along the shape of the bundle band 71 before the bundle line. The wires 100 aligned in this way can be bundled in a state where the gap with the bundle band 71 is minimized. Thus, the wire 100 when handling after flux lines bundled band 71, collapses the outline S ₁ of the entire cross section of the wire 100 is substantially circular wire 100 bundled wire band within 71 moves displaced respectively The bundled band 71 can always maintain a sufficient bundled state.

As described above, according to the wire rod winding device according to the first embodiment, the shafts 4a to 4d have the curved portions 41a to 41d, and the wire 100 is wound around the curved portions 41a to 41d. Therefore, envelope S ₁ of the entire cross section of the wire 100 wound on the shaft 4a~4d becomes substantially circular, after flux lines bundled band 71, it is possible to maintain a sufficient wire bundle state.

1 and 2 show a configuration having four shafts, the number of shafts may be three, for example, and is not limited to that shown.
Moreover, you may comprise so that the cross section of the curved parts 41a-41d at the time of cut | disconnecting the shafts 4a-4d by the plane containing an axis | shaft may dent especially in a semicircle among arc shapes. In this way, outline S ₁ of the entire cross section of the wire 100 wound around the shaft 4a~4d becomes close to a circle, it is possible to maintain a more adequate bundled state. In this case, based on the distance between the shafts 4a to 4d and the length of the wire 100 that is to be bundled together by the bundle band 71 and combined into one, the number of cross sections of the wire 100 can be reduced to the shafts 4a to 4d. Is assumed to be wound (in the example of FIG. 3B, eight cross sections are wound), and when the expected number of wires 100 are bundled, the number of wires 100 corresponding to the number of wires 100 is bundled. of the shape of the circle of semicircle can outline S ₁ of the entire cross-section taken, it is sufficient dent.
Alternatively, the straight portions may be eliminated, and the shafts 4a to 4d may be configured by only the curved portions 41a to 41d.
In addition, portions of the bending portions 41a to 41d where the wire 100 is not wound (for example, the bending portions 41a to 41d located on the left side in FIG. 3) may have a linear shape without being a bending portion.

Embodiment 2. FIG.
The wire winding device according to the second embodiment of the present invention differs from the wire winding device according to the first embodiment in that a plurality of plate members 8a to 8d described later are provided instead of the plurality of shafts 4a to 4d. . Other configurations are the same as those of the wire winding device according to the first embodiment, and will be described with reference to FIGS. 1, 2, and 3.
In FIG. 4, the some board | plate materials 8a-8d with which the wire winding apparatus which concerns on Embodiment 2 of this invention is provided are shown with a perspective view.

The plate members 8a to 8d are plates having a substantially rectangular surface, and the end portions 81a to 81d are fixed to the support plate 3 shown in FIG.
Further, the plate members 8a to 8d have curved portions 82a to 82d that are recessed in a direction perpendicular to the rotation axis of the motor that rotates the pedestal 1 and whose cross sections are arc-shaped uniformly. The curved portions 82 a to 82 d are recessed toward the rotation axis of the motor that rotates the pedestal 1.

  The operation of winding the wire rod 100 by the wire winding device having the plurality of plate members 8a to 8d as described above is described in the first embodiment except that the wire rod 100 is wound into the plurality of plate members 8a to 8d. The operation is the same as that described above. Further, similarly to the first embodiment, the sizes of the curved portions 82a to 82d are designed so that the wire 100 is accommodated in the curved portions 82a to 82d and wound.

  Since the plate members 8a to 8d have curved portions 82a to 82d, and the wire 100 is wound around the curved portions 82a to 82d, the plate members 8a to 8d are wound around the plate members 8a to 8d in the same manner as shown in FIG. The outline of the entire cross section of the wire 100 is substantially circular. That is, the wire rods 100 are aligned in a shape along the shape of the bundle band 71 before the bundle line. The wires 100 aligned in this way can be bundled in a state where the gap with the bundle band 71 is minimized. Therefore, when the wire rod 100 is handled after being bundled with the bundle band 71, the wire rod 100 is displaced in the bundle wire band 71 and the outline of the entire cross section of the substantially circular wire rod 100 is destroyed. The bundled band 71 can always maintain a sufficient bundled state.

  As described above, according to the wire winding device according to the second embodiment, the same effect as the effect shown in the first embodiment can be obtained. Further, compared with the shafts 4a to 4d shown in the first embodiment, the curved portions 82a to 82d included in the plate members 8a to 8d are perpendicular to the rotation axis of the motor than the curved portions 41a to 41d included in the shafts 4a to 4d. Long in any direction. Therefore, the overall shape of the entire cross section of the wound wire rod 100 can be made into a substantially circular shape in many parts, and even after being bundled by the bundle band 71, it is possible to maintain a stable and sufficient bundled state. .

In addition, although the structure which uses four board | plate materials was shown, it does not restrict to this number. For example, the number may be three.
Moreover, you may comprise so that the cross section of the curved part 82a-82d of board | plate materials 8a-8d may be dented in a semicircle especially in circular arc shape. By doing in this way, the general shape of the whole cross section of the wire 100 wound around the board | plate materials 8a-8d becomes near circular, and it becomes possible to maintain a sufficient bundling state. In this case, based on the interval between the plate members 8a to 8d and the length of the wire member 100 that is to be bundled together by the bundle band 71, the number of cross sections of the wire member 100 is determined as the plate members 8a to 8d. Assuming that the wire 100 will be wound around, the rough shape of the entire cross section of the wire rod 100 for the assumed number of wires may be recessed into a semicircular shape when aligned in a circle.
Moreover, in plate material 8a-8d, a plane part may be eliminated and the whole may be comprised as curved part 82a-82d.

In addition, although the structure which has four elastic members was shown, it does not restrict to this number. For example, the number may be three.
Moreover, only the part around which the wire 100 is wound may be made of rubber or the like among the elastic members 9a to 9d, and the other part may be made of a material that hardly undergoes elastic deformation.
In addition, the elastic members 9a to 9d are not formed into a bar shape with a uniform cross section, and the diameters are gradually reduced once in the axial direction as in the shafts 4a to 4d, and gradually return to the original diameter again. The shape may include the curved portions 41a to 41d. Alternatively, the elastic members 9a to 9d may have a plate shape instead of a rod shape.

Further, within the scope of the present invention, the invention of the present application can be freely combined with each embodiment, modified with any component in each embodiment, or omitted with any component in each embodiment. .
Moreover, you may perform all or one part of each process, such as winding and bundling which the wire rod winding device which concerns on Embodiment 1-3 performs.
